This image from the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows the patch of rock cleaned by the first use of the rover's Dust Removal Tool (DRT). The tool is a motorized, wire-bristle brush on the turret at the end of the rover's arm. MAHLI took this image from a distance of about 10 inches (25 centimeters) after the brushing was completed on this rock target called "Ekwir_1." Image courtesy of NASA
